Abstract

A reconfigurable wide band phased array antenna for generating multiple antennabeams for multiple transmit and receive functions. The antenna array comprises multiplelong non-resonant TEM slot antenna apertures with RF MEMS switches disposedwithin the slots. The RF MEMS switches are positioned directly within the feed linesacross the slots to directly control the coupling of RF energy to the slots. Mulitple RFMEMS switches are used within each slot, which allows multiple transmit/receive functions and/or multiple frequencies to be supported by each slot. The frequencycoverage provided by the slot antenna has a greater than 10:1 frequency range.
